About The Position

At Relativity Space, the success of our Terran R vehicle operations relies on software systems that are robust, well-integrated, and rigorously tested. The Software Systems Engineering team is a multidisciplinary function responsible for ensuring that the integrated software system that supports vehicle operations is functional, scalable, performant, and ready for test and launch activities in alignment with the program schedule and risk posture. We bridge the gap between vehicle software, ground systems, and hardware teams to ensure reliable end-to-end system functionality. Our focus includes system-level requirements development, safety engineering and analysis, software-hardware integration, risk management, system-level debugging, launch-readiness verification, and operations support. We play a critical role in mission success by ensuring all software components work seamlessly across the full stack—from control centers to the vehicle in flight.
Own and develop Software system-level requirements, drive consensus and alignment among stakeholders, and ensure requirements traceability to verification and validation activities
Identify, document, escalate, and manage software risks to the operational vehicle system; relentlessly drive strategic and thoughtful mitigations that balance complexity, schedule, and operational risk
Own and drive Software system-level design verification and validation activities, including development and execution of test matrices and test plans with traceability to requirements, and identification of pass/fail criteria
Define and build process around software configuration and change management and related tooling; provide critical feedback and input to tooling development teams; help educate users and software development teams
Support mission-critical Software system certification and licensing deliverables that include failure mode analyses and verification artifacts
Support test and launch activities on behalf of Software -- coordination of integration and test activities between Engineering and Operations, anomaly investigations, pre-test/launch readiness evaluations, post-test/launch data reviews, and on-console support
